STENCIL AND METHOD OF MAKING AND USING THE SAME.

Application filed February 14, 1921.

To all whom it may concern:

Be it known that I, HUXLEY D. KEM. citizen of the United States,residing at ortland, in the county of Multnomah and State of Oregon,have invented certain new and useful Improvements in Stencils andMethods of Making and Using the Same, of which the following is aspecification.

This invention relates to stencils and the method of'makingand using thesame, and particularly to such stencils and methods as are employed inthe placing of paint upon cardboard, wood, metal,'cloth, or othermaterial, in the form of letters, pictures, or other characters ordesigns.

Heretofore, in making stencils to eliminate ties between the parts, ithas been a practice to employ a screen having a sensitive gelatinecoating and to imprint the design upon this coating after which theprint is developed and the portion to be stencilled through is washedout, the insoluble portions exposed to the light remaining in the screenand outlining those portions washed out. This process requires a newscreen of bolting silk or similar material for each stencil,necessitates the use of a complete and finished opaque drawing ontransparent material for the printing, by exposure tothe light, of eachstencil, requires a dark room, chemical solutions, and a large tank ofsufiicient size to take the largest stencil frames; and, takes from 24to 48 hours to prepare the stencil, exclusive of the time required forpreparation of the complete opaque drawings.

With this in mind it is an object of my invention to eliminate thesensitive coating of the screen and the consequent delay and workinvolved in the complicated process; and, to provide a stencil andmethod of making and using the same in which a single frame having abolting silk screen stretched thereacross can-be successively employedfor different stencils and can-be used until the screen is worn through.

A further object is to eliminate the necessity for making completedopaque drawings, and to provide for completion of the stencils fromsketches.

Yet another object resides in so carrying out the making of the stenciland the using of the same that a perfect registry with previouslyprinted or stencilled matter can be obtained, and that these steps carryforward Serial No. 444,851.

in a manner to insure most expeditious completion and use of a stencil.

With these and other objects in view, which will be apparent from thedrawings, specification and claims, this invention in cludes certainnovel features of construction and combinations of parts and such stepsand sequence of procedure as will now be set forth.

In the drawings:

Figure 1 shows a picture painted in a dark and contrasting color throughthe use of my stencil and in accordance with my improved method. i

Fig. 2 is a fragmentary top side View of a screen carrying a stencil forthe dark color.

Fig. 3 is a. perspective view of a squeegee which may be used in workingthe paint over the stencil.

Fig. 4 is a lower side view of a stencil prepared for the contrastingcolor of the picture as shown.

Fig. 5 is a sectional view on line 5-5 of Fig. 4.

In carrying out my invention a flat rectangular frame 1, of wood orother suitable material, has the. screen 2, of Millers bolting silksimilar to #70 grit gauze, stretched and secured over one side thereof.This frame is mounted for swinging movement above a table top 3 by theuse of hinges 4, or is otherwise placed and mounted so that it can beconveniently placed upon the cardboard, wood, metal, cloth, or othermaterial, to which the paint is to be applied, and can as readily beraised therefrom in a manner to avoid smearing after the paint isapplied. In the arrangement as shown gauge pins can be placed in thetable top 8 and large or small runs of the single stencil design can beaccurately made upon any material.

In Fig. 1 I have shown a design in a dark and a contrasting color, whichdesign includes letters and other painting in each of the colors, andfor each of these colors the screen 2 is used, the same gauge pins beingemployed for each operation on the card 5, thus insuring a perfectregistry. A separate stencil must of course be employed in placing eachof the colors upon the card, and these stencils can be quickly andaccurately prepared from pencil or other sketches.

In makin the stencil tracing paper, pref erably an oi ed or parchmentpaper, is placed over the sketch or drawing to be reproduced and thedesign is cut out of the paper and discarded, substantially as in makinganordinary stencil, with the exception that it is unnecessary to leaveties between the parts. The card or article to be stencilled is placedupon the table 3 in a correct position under to be applied. The centersof the letters, as

indicated at 7 in Fig. 4, and other loose pieces of the stencil sheetare put where they belong, and the frame 1 is then swung down to bringthe screen 2 against the stencil sllieet, the screen holding the loosepieces in ace.

Paint of the desired color is poured into the frame and is pulled acrossover the screen by the use-of a squeegee similar to that shown in Fig.3, the flexible wiper'S fixed in the handle 9 being used to smooth andspread the paint. It is preferable that the stencil sheet be made of aize to turn up slightly at the edges of the frame, as in this Way theblank of the stencil is presented at all points Where the paint is to bestopped and paint will penetrate only through the cutout openings. Asthe paint is worked over the screen 2 from the inner side by the use ofthe squeegee it causes the stencil sheet to adhereto the screen andattaches the loose pieces to be held in their proper positions, thisadhesion being such that when the frame is raised the stencil sheetstays with the screen. Where there is a tendencyfor loose pieces toseparate from the screen this can be remedied by the use of an adhesive.

After a run of the particular stencil is completed and the desirednumber of copies has been obtained the paint is washed from the screenand the stencil sheet can be re-v moved and any spots of adhesive washedout. The screen is then in condition to be used with other stencildesigns. By the use of this stencil and process several differentdesigns can be made with the same screen in a single day, withoutremoving the frame from the table or changing the gauge pins, and thescreen can be used until itis worn through.

While, in the foregoing, I have described specific embodiments, and havementioned only certain possible modifications it will be appreciatedthat in practice I do not limit myself to such specific details asherein set forth, but may resort to any practical modifications fallingwithin the scope of the invention as defined in the appended claims.

I claim: V
